WILLIAM H. LANG, OF- CHIGAGO, ILLINOIS, ASSIGNOB.

OF ONE-HALF TO GEORGE W.

PHILLIPS, OF CHICAGO, ILLINOIS.

AUTOIEATIC SKIP-BUCKET LOADING DEVICE.

Application filedMarch 12, 1923.

To all whom it may concern:

Be it known that I, WILLIAM H. LANG, a.

citizen of the United States, and a resident of the city of Chicago,county of Cook, and

State of Illinois, have invented certain new and useful Improvements inAutomatic Skip-Bucket Loading Devices, of which the following is aspecification.

My invention relates to improvements in automatic skip bucket loadingdevices. and has for its principal object the provision of an improvedconstruction of this character which will be highly eiiicient in use andeconomically in manufacture.

I aim among other things to provide certain combinations of elements andparts operable by a skip bucket of the ordinary construction forautomatically filling the bucket and for automatically interrupting thesupply of material discharged into the bucket, the device beingespecially designed for use in connection with a. skip bucket adapted tobe manipulated in a vertical plane between skip guides of the ordinaryconstruction.

Other objects will appear hereinafter.

Theinvention consists in the combinations and arrangements of partshereinafter de scribed and claimed.

The invention will be bestunderstood' by reference to the accompanyingdrawings forming a part of this specification, and in which,

Fig. 1, is a side elevational view of the loader embodying theinvention;

Fig. 2, is a front elevational view of the same;

Fig. 3, is a sectional view taken substantially on line 33 of Fig.2, and

Fig. 4, is a sectional view taken substantially on line 41-4 of Fig. 2.

In carrying the objects of the invention into effect and with referenceto the accompanying drawings-I associate my automatic skip bucket loaderwith a hopper 10 of suitable shape and construction designed espe ciallyto receive the material to be loaded into the skip bucket. The hopper 10is provided chute 12 having its end 18 inserted in the opening 11 andfixed thereto by any suitable means. The hopper 10 is preferably of thetype having its interior conical in shape terminating around the opening11 so that 55 by the laws of gravity the material in the apron 29 havingits wall the bevelled with a discharge opening 11 and a 1 Serial No.624,442.

hopper will work toward the opening 11, this construction avoids thenecessity of pushing the material to and through the discharge opening.In Fig. 3 I prefer for reasons to be hereinafter understood to bevel theedges indicated at 14 of the vertical side walls 15 of the chute 12. Thechute 12, as shown, is of the open top type, however a closed top typechute or any other chute of the ordinary construction will serve thepurposes as well.

In Fig. 1, 16 indicates a skip bucket mounted to be verticallymanipulated between the skip guides of a shaft, not shown, by the usualmeans and of the ordinary construction. On opposite sides of the bucket16 and in spaced relation with respect to the adjacent sides of thebucket are verticallyextending guides 17 and 18 providing channels 19,the guides being provided with attachment means indicated at 20 andbracing means indicated at 21. The position or location of the guideswith respect to the bucket is such that a portion of the bucketindicated at 22 will proiect beyond the outer corresponding faces of theguides as best shown in Fig. 1. A yoke 23 including a transverselypositioned rod member 23 having its opposite ends 24 extending into thechannels is adapted to reciprocate vertically with respect to the guidesin a manner to be more fully hereinafter understood. Connected to themember 23 are spaced links 24 and 25 having integral stops 25" formed atone end thereof and pivotally connected at the other ends to a rodmember 26 pivotally connected to an auxiliary chute 26 as at 27, Fig. 3.The auxiliary chute 26 is pivotally connected to the chute 12 as at 28.The chute 26 is designed especially to interrupt the passage of materialthrough the chute 12 to the bucket 16 and for this pur pose it isprovided with an extension or 30 arcuate in shape and corresponding tothe contour of edges l i of the vertical walls of the chute 12. Thechute 26 is further provided with side walls 31 and top and bottom walls32 and 33 respectively and with a discharge opening 34- The wall 32 extends to a point rearwardly from the discharge opening to provide a stopedge 35 which is adapted to rest upon the top edges of the verticalwalls of the main chute when the auxiliary chute is in the positionillusas the bucket remains in trated in dotted lines in Fig. 1. hen thechute 26 is in the position shown by dotted lines in Fig. 1 the chute isretained in this position by means of weights 36 preferably carried bythe walls 31.

It will be readily seen by inspection of Fig. 1 that when the chute 26is in the position shown by dotted lines the wall 30 of the aproninterrupts the passage through the chute 12 and when the chute 26 is inthe position best illustrated in Fig. 3 the passage through the chute 12is unobstructed and the material from the hopper 10 free to pass intothe skip bucket 16.

The operation of my automatic skip bucket loading device is as follows:The bucket 16 upon being moved downwardly between the usual skip guidescomes into contact with the member 23 of the yoke 23, the member 23 uponfirst coming into contact with the bucket is in the position shown indotted lines in Fig. 1 and the chute 26 is in the position shown indotted lines in that figure. Due to the down-force of the bucket on theyoke 23 the auxiliary chute is caused to pivot into operative positionand the wall 30 of the apron 29 moves with the auxiliary chute fromobstructing the passage of material passing from the hopper to thebucket. As long the position illustrated in Fig. 1 in full lines thechute 26 will be held in operative position thereby, but upon verticalmovement of the bucket the top of the bucket comes into contact with thewalls of the auxiliary chute and as the bucket moves upwardly the chutealso will pivot upwardly. The bucket continues to force the chute 26 topivot upwardly until a point is reached where further pivotal movement,is brought about by the weights 36.

It will be seen that no manual labor is.

necessary to operate the chute 26 to bring it into operative positionand to move it again to its inoperative position as this operation isaccomplished solely by the skip bucket.

\Vhile I have illustrated and described the preferred formofoonstruction for carrying my invention into effect, this is capable ofvariation and modification without departing from the spirit of theinvention. I, therefore, do not wish to be limited to the precisedetails of construction set forth, but desire to avail myself of suchvariations and modifications as come within the scope of the appendedclaims.

Having described my invention, what I claim as new and desire to secureby Letters Patent is z 1. An automatic loading device for a skip buckettraveling between vertical guide rails, said device comprising a fixedchute, a chute pivoted to said fixed chute and having an extension witha curved wall to close the passage provided by said chutes, a yokeswingably mounted on said pivoted chute, for operating said chute, and atransverse rod in said yoke and having its ends traveling in said guiderails, said rod being engaged by the bottom of said bucket travel ing insaid guide rails for swinging said pivoted chute with its closing meansto provide a continuous passage through said chutes.

2. An automatic loading device for a skipbucket traveling in verticalguide rails, said device comprising a fixed chute, a chute pivoted tosaid fixed chute and having an extension with a curved wall for closingthe passage through said fixed chute, a front and top wall on saidpivoted chute arranged for preventing material from overflowing saidbucket when said chute is lowered and also adapted to engage said fixedchute for. holding said pivoted chute when in its raised position, and ayoke with a transverse rod swingably mounted on said pivoted chute, saidrod traveling in said guide rails and being engaged by said bucket forswinging said pivoted chute with its curved wall to open the passagethrough said chutes.

3. An automatic loading device for a skip bucket traveling in verticalguide rails, said device comprising a fixed chute, .a chute pivoted tothe bottom of said fixed chute and having an extension with a curvedwall for closing the passage through said fixed chute, a front and a topwall on said pivoted chute arranged for preventing material fromoverflowing said bucket when said chute 1s lowered and also adapted toen- In testimony whereof I have signed my name to this specification inthe presenc of two subscribing wltnesses.
